摘要: This paper reports a study on the effects of concentration and molecular structure amines antiwear properties TBP, TCP TBPi, evaluated with four-ball machine. It was found that reduce P-containing additives in order primary>secondary>tertiary amine, critical amine exists at which lose their properties. XPS analysis indicated competitive adsorption onto rubbed surface causes reduction additives.
